As of 1st July '09 I am now the Senior Research Officer and Laboratory Manager
Inorganic Chemistry here in the department providing support for the
department's X-ray instrumentation and support to Head of Section,
Prof. Ivan Parkin. Until recently I've worked closely with
Dr Jeremy Cockcroft
on wide applications of Powder X-Ray Diffraction (PXRD)
and the development of PXRD equipment. He currently has a
Stoe StadiP capillary geometry system and a Siemens
(now Bruker AXS)
D500 reflection set up. Along with Jeremy, I have
developed the Stoe for high resolution and high/low temperature data
collection. We have adapted an Orange Cryostat for liquid helium temperatures
and added a Cryojet for more routine liquid nitrogen temperatures.
The Stoe StadiP and Siemens D500 in their natural environment:
Although both tools are valued very highly, if one clicks
here one can understand why we might favour the
transmission (Stoe) machine over the more conventional "flat plate" (Siemens)
Additional to our equipment is a Jeol scanning electron
microscope with an ED detector for elemental analysis which has proved very
useful for our work.

Interests to date include drug polymorphism investigations to establish
crystallographic purity and posible structure of a variety of common-use
drugs. This includes dynamic temperature diffraction and also overlaps with
Prof. Sally Price's group studying this phenomenan from the computational side.
A recent collaboration with Dr. Jawwad Dar's group has lead us into
nanopartical studies and the first ever user-data collection from the new
powder diffraction beam-line at the Diamond Light Source.
As an analytical tool, powder diffraction necessarily leads to an eclectic mix
of topics and materials for study. Past examples include the
Roman Sevso Silver,
cladding on telephone cables, asbestos removed from buildings, cow shed
cleaners, human bone/urinary calculi composition and antient Egyptian bronzes.
I shall include information about the other diffraction sets in the department
in due course.
